  1. JISC Information Environment Service Registry (IESR) Ann Apps MIMAS, The University of Manchester, UK

  2. Outline • IESR content description • IESR services • Using IESR • The future of IESR • Scope of IESR • Distributed registry model Distributed Services Registries Workshop

  3. IESR Content • Descriptions of: • Collections of resources • Informational Services that provide access • Agents: Owners / Administrators • Transactional Services • Supplied by resource providers • Check by IESR content manager Distributed Services Registries Workshop

  4. IESR Entities Collection provides access owns Service Agent administers Distributed Services Registries Workshop

  5. IESR Entity Description • Entities identified with URI • Described by metadata • Based on open standards • IESR terms defined in IESR namespace • Metadata defined by Application Profile • Semantics • Occurrence • Searchable Distributed Services Registries Workshop

  6. IESR Collection Metadata • Based on RSLP Collection Description Schema • Simplification for electronic resources • Consistent with standards development Distributed Services Registries Workshop

  7. Vocabulary Encoding Schemes • Defined in Application Profile • Single backbone subject scheme • Dewey Decimal Classification System • Other common vocabularies supported • iesr:usesControlledList • IESR defined list (extensible) • terminology service; item level search Distributed Services Registries Workshop

  8. Distributed Services Registries Workshop

  9. IESR Service Metadata • More than RSLP CD ‘locator’ • Bespoke IESR scheme, uses open standards • Single access method: • Z39.50, SOAP, OAI-PMH, Web/CGI • Location URL • Interface property for some service types Distributed Services Registries Workshop

  10. Distributed Services Registries Workshop

  11. Other Service types • SOAP: • Locator: access URL • Interface: WSDL • OAI-PMH: • Locator: BaseURL • Interrogate service (Identify) for details • OpenURL: Locator: BaseURL • Web CGI: Interface: arguments • Web page: Locator: URL Distributed Services Registries Workshop

  12. IESR Agent and Administrative Metadata • Agent: contact details • Administrative: • Included with every entity • IESR includes: • creating organisation, publisher: IESR • latest modification date • rights to reuse descriptions Distributed Services Registries Workshop

  13. IESR Creative Commons Licence • All IESR records licensed under a Creative Commons licence: • Non-commercial (freely available) • Share-alike (maintain same licence) • Attribution-required (attribute provenance) • Suppliers agree to this licence • http://creativecommons.org Distributed Services Registries Workshop

  14. IESR Services • Z39.50 • Search via Bib-1 • SUTRS; XML • OAI-PMH for harvesting • Web Services SOAP (planned) • SRW; NISO VIEWS • RSS (later) • UDDI (under investigation) • Web Search and Browse Distributed Services Registries Workshop

  15. IESR XML • Composite Collection record via Z39.50: • Collection • All services that provide access • All agents: • Owners of collection • Administrators of services • Single entity record via OAI-PMH • Simple Dublin Core for Interoperability Distributed Services Registries Workshop

  16. Using IESR • Portal • amalgamated set of resources • Metasearch on behalf of user • Social Science portal discovers collections • Provides cross-search to end-user • Portal builder doesn’t need to know about all resources • Users discover collections unaware of Distributed Services Registries Workshop

  17. Using IESR • Portal: Harvest IESR records • Local service registry • Knowledgebase (convert to appropriate format) • Local configuration file • Portal: Link to Web Search - general resource discovery • RSS Aggregator: • news feeds; data alerts • Reuse collection description Distributed Services Registries Workshop

  18. IESR Future • Current phase until July 2006 • More and updated content • New IESR services • Demonstrating viable IESR use • Maintenance of metadata schema • Practical application of collection description • Persistence of content Distributed Services Registries Workshop

  19. Scope Issues • Scope of IESR: JISC, UK, international? • User community requirements • Scalability • Is data maintenance and QA manageable? • Service-oriented architectures implications • Data ownership • Who describes commercial resources? • Who describes free stuff? Distributed Services Registries Workshop

  20. More Scope Issues • Aggregated content • Single description of resource desirable • New types of resources • Electronic journals – latest issue? • E-learning resources • Institution resources • Library catalogues • Repositories – do these need own registry? • Institution profile Distributed Services Registries Workshop

  21. Portal View of IESR • Institutional Portal • May prefer to maintain own registry • Library Portal • Includes ‘paid for’ knowledgebase • Institution subscriptions data • Vendor view of IESR • Provide competition? • Be a source of information? • Take over maintenance? Distributed Services Registries Workshop

  22. Horizon Scanning • Distributed model • Each node describes own resources • JISC data centres; Publishers; Aggregators; Institutions • Improves maintenance / scalability • Not everyone will want own registry • Will coverage be a problem? • May still need UK HE/FE registry Distributed Services Registries Workshop

  23. Searching Virtual Registry • Metasearch (Z39.50 / SRW) • May be too high a barrier for portals • UDDI • Aggregate by OAI-PMH harvest Distributed Services Registries Workshop

  24. Aggregated Registry • Community Registry: selective view • UK academic registry: could be IESR clone • International registry • Biosciences registry • Registry of freely available resources • How to find registries? • Registry of registries? Distributed Services Registries Workshop

  25. More issues • Interaction with other shared services • Sharing collection descriptions • Who creates community registries? • Who describes free resources? • Terminology backbone • Use rights • Encouraging use • Software for node registries Distributed Services Registries Workshop
